Thermocouple and Strain Gauge Reference Design
Intersil’s Analog Mixed Signal Sensor Signal Conditioning w/ Renesas RL78 Microcontrollers

Reference Designs and Evaluation Platform

Intersil is demonstrating practical sensor solutions for thermocouple, pressure and strain gauges for industrial, medical and data acquisition applications. These solutions include a working sensor, signal conditioning circuits, and a Renesas microcontroller. The reference design and evaluation platform is intended for evaluation by circuit design engineers for early prototype development.

Pressure and Strain Gauge Sensor Solutions with an Renesas RL78

Intersil is demonstrating a bridge solution that is able to extract small sensor signal from a high voltage signal common mode of 10V or higher and perform signal conditioning (gain, filtering, and digital conversion) and feed it into a Renesas RL78 microcontroller for further digital processing. The Intersil solution highlights a 24-bit Low Noise Precision signal conditioning that includes the following complete analog-to-digital frontend: 40V Instrumentation Amplifier and ADC driver, 24-Bit Delta Sigma Converter, Low Noise Voltage Reference and others. Software interface is included for evaluation purposes.

Thermocouple Temperature Sensor Solution with an Renesas RL78

Intersil is demonstrating a K-type Thermocouple temperature sensor design with cold junction compensation circuitry. The signal conditioning circuit features Intersil’s leading a zero drift, chopper stabilized amplifiers, and a 24-bit low noise Delta Sigma Converter. The analog signal is processed by a Renesas RL78. Software interface is included for evaluation purposes.
